Climate change can threaten male fertility – according to a new study by the University of East Angiele.
New findings were published today in the journal Nature Communications To reveal that the heating axis is damaging insects-negative impacts for the generation of generations.
According to the research group, male infertility during the insulation helps explain why climate change is such an impact on species populations, including climate-related destruction in recent years.
Professor Met Gag, Professor of Research Group, said: "We know that biodiversity is under the climate change, but it is difficult to find concrete reasons and sensitivities.
"We have shown in this work that sperm function is a particularly sensitive feature when the atmosphere starts and the model system represents a huge number of global biodiversity.
"Since sperm function is necessary for reproduction and population survival, these conclusions can provide one explanation of why the disease is under the climate change.
"The warm atmosphere will be more fragile and dangerous, with extreme events such as heatwaves becoming more frequent, intense and widespread.
"Habitats are particularly damaging to extreme weather events, as local destruction is known when the temperature changes are very intense, we want to know why this and one answer can connect to sperm."
The research team has investigated the red flourTribal citrus) Explore the effect of simulation fluids on male reproduction.
The beetles are subject to standard controls or five-day heating temperatures that are high on thermal optimum of 5 ° C to 7 ° C.
After that, a variety of experiments evaluated the reproductive success, sperm function and the quality of the offspring.
Heat swelling followed
The team concluded that the heated offspring may present and the second heat of almost sterile males.
Women, on the contrary, were unjustified conditions. However, women's reproduction was indirectly because experiments demonstrated that thermal insulin was responsible for using inert sperm in women's reproductive trauma.
After experimental heat, men decreased sperm from three to four quarters and then emerged of any sperm that was given to women and more deaths.
Kirs' sales, a postgraduate researcher who led research, said: "Our research shows that the heatwaves halve male reproductive fitness, and it was surprising how consistent the effect was."
The group also studied the causes of male vulnerability. The feeling of air caused the influence of male sexual behavior in men who are gradually using as control.
Heaters damaged generations
"The impact of two influences on the impact of influencing men and the impact of heat on future generations," – said the sale.
"When men were in the 10 days during two heat phenomena, their offspring were less than 1 percent of the control group, insects in nature could have multiple heater events that could result in the productivity of the population if the male reproduction can not be adapted or restored."
The study also showed that the offspring begins with thermal insulating saving or the duration of their sperm in life – a few months.
It also affects the reproduction of the male produced by the mother or the sperm that was caused by the condition of the heating condition. The brothers were less able to merge potential partners and have fewer offspring.
The researchers warn that this could lead to additional pressure on those populations that are already suffering from climate change.
"Beetles think they are a quarter of biodiversity, so these results are very important to how the species impacts climate change: the study has shown that heat shock can damage male reproduction in warm blood animals, leads to infertility mammals," added sales.
The researchers hope that the effect may include varieties of vulnerability, and eventually the community sharing and conservation measures.
